Mithril rock

A mithril rock, also called mithrite[1], is a rock that can be mined through the Mining skill to obtain mithril ore in various places throughout RuneScape. Mithril rocks can be mined with a Mining level of 55 or higher, granting 80 Mining experience and one mithril ore.

Hobgoblin Mine in level 30-35 Wilderness contains the greatest amount of mithril rocks. It also has several adamantite rocks, but like all Wilderness locations, player killers are always on the prowl, so take necessary precautions, and never bring anything you can't afford losing.
